In this study, performance of the WEPP model in simulating runoff from rangeland sites at Reynolds Creek Experimental Watershed in southwestern Idaho, USA, was evaluated using three spatial scales; small plots (0.10 msuperscript 2), large plots (33 msuperscript 2), and a watershed (1.25 ha). For small plots, results show that significant small-scale variability in Ke values exists in rangeland. Optimized Ke was positively correlated to organic carbon and negatively correlated to bulk density.
